Definitions

  • This invention relates to a device for opening screwed lids and the like, comprising a handle having two portions displaceable relative to each other, and a flexible loop means to be positioned around the lid and tightened against it.
  • the present invention facilitates the opening of screwed lids by allowing a flexible loop to be tightened around the lid and locked in the tightened state in an extremely simple way.
  • the device according to the invention is characterized in that the handle portions are interconnected so that they are moveable towards and away from each other, and in that the loop is arranged to pass between the handle portions.
  • the handle portions have locking means cooperating with each other so as to lock the loop means to the handle to facilitate opening the lid.
  • the loop can be tightened in its final position around the lid and locked in this position by a single movement: by squeezing the handle portions closer to each other.
  • This squeezing movement is so natural that the device should alleviate the problems associated with conventional devices of this type.
  • the device is especially simple to use if one end of the loop means is fastened to one of the handle portions.
  • the handle is elongated and the loop means is fastened to one handle end, it is preferable to interconnect the handle portions by means of a hinge positioned at the handle end opposite the end to which the loop means is fastened.
  • the handle portions can be made moveable relative to each other, as required by the invention, simply by interconnecting the handle portions at the end remote from the loop. This solution is also recommended for the reason that the handle portions can thus easily be arranged to move over the greatest distance relative to each other at the handle end close to the loop. In that case, the loop can be tightened around the lid in an amount greater than the relative movement of the regions of the handles which are actuated by the user.
  • the device can in a simple way be made to operate in the right order, that is, the loop is first locked in position and then tightened around the lid.
  • the locking means of the handle prefferably be formed by a cam provided in one handle portion and a support surface provided in the opposite handle portion.
  • the cam As the loop surface to be positioned against the lid is often made uneven to achieve good gripping properties, it is preferable to position the cam in the handle portion to which the loop means is connected.
  • the device according to the invention can be formed as an integral body if it is made of a suitable material, such as plastic.
  • FIG. 1 is a perspective view of a device according to the present invention.
  • FIGS. 2 and 3 are longitudinal sectional views of the device before and after the loop is tightened around the lid.
  • the opening device or hand tool 100 for screwed lids or rotatable object 14 shown in the figures comprises an elongated handle 1 and a flexible loop means 2.
  • Handle 1 has a first handle portion 3 and a second handle portion 4.
  • First handle portion 3 includes a proximal end 16 and a distal end 18 opposite proximal end 16.
  • Second handle portion 4 includes a second proximal end 20 and a second distal end 22 opposite proximal end 20.
  • First and second handle portions 3, 4 are interconnected at distal end 18 and second distal end 22 by a hinge 5.
  • Loop means 2 includes a loop end 6 attached to first handle portion 3 at proximal end 16.
  • Loop means 2 further includes a free end 7 having a thickening portion.
  • Hinge 5 allows first and second handle portions 3, 4 to be moved toward and away from each other substantially in the direction of the tangent at the points of contact between handle portions 3, 4 and lid 14.
  • hinge 5 allows first and second handle portions 3, 4 to be moved towards and away from each other substantially perpendicular to a longitudinal axis 30 of handle 1.
  • Second handle portion 4 is U-shaped in cross-section so that it forms a trough 8 opening towards first handle portion 3.
  • First handle portion 3 in turn has such dimensions that it can be fitted at least partly into trough 8 of second handle portion 4.
  • the outward surface of the second handle portion 4 is provided with an opening 9 close to hinge 5. Opening 9 is in communication with trough 8.
  • loop means 2 passes through trough 8 and opening 9 so that its free end 7 is positioned outside handle 1. When the device 100 is in a position for use, loop means 2 is thus positioned partially between first and second handle portions 3, 4.
  • the first handle portion 3 is provided with a projecting cam 10 in its surface facing the bottom of trough 8.
  • Cam 10 is positioned close to distal end 18 of first handle portion 3 near hinge 5.
  • Trough 8 of second handle portion 4 includes a suspect surface 11 located opposite to cam 10.
  • Second handle portion 4 is provided with projections 12 and 13 which extend toward and encircles first handle portion 3 forming a stop thereby limiting the movement of handle portions 3 and 4 away from each other.
  • the opening device 100 operates in the following way. Loop means 2 is drawn out of handle 1 to such an extent that it reaches loosely around lid 14, see FIG. 2. At this stage, hinge 5 keeps the first and second handle portions 3, 4 as far from each other as allowed by projections 12, 13. When handle 1 is then squeezed by hand against the action of hinge 5, first handle portion 3 enters trough 8 of second handle portion 4. As a result of the movement of first and second handle portions 3, 4 towards each other, cam 10 presses loop means 2 against support surface 11 of second handle portion 4, thus locking loop means 2 so that it is not able to move in its longitudinal direction relative to handle 1 i.e., substantially along axis 91.
  • proximal end 16 of first handle portion 3 and second proximal end 20 of second handle portion 4 move closer to each other substantially in the direction perpendicular to longitudinal axis 30 of handle 1, which causes loop means 2 to be tightened around lid 14.
  • Handle 1 is squeezed until loop means 2 has tightened appropriately around lid 14, see FIG. 3, whereafter handle 1 is turned in the opening direction of lid 14 to open lid 14.
  • first and second handle portions 3, 4 may be quite different from that shown in the figures, and hinge 5 may be replaced e.g. by flexible fastening means positioned substantially centrally in the handle portions.
  • the joint between the handle portions may also be such that one handle portion remains immovable relative to the lid 14 and only the other portion moves perpendicularly or obliquely towards the first-mentioned portion when the loop is tightened.
  • Cam 10 and the support surface 11 can also be replaced with other arrangements, and cam 10 and support surface 11 may be formed in regions of the handles other than those illustrated in the Figures.
  • Parts 2, 3 and 4 may form an integral body or be separate bodies fastened to each other.
  • Loop means 2 may also be fully separate from handle 1, in which case its both ends pass between the first and second handle portions 3, 4.
  • the device 100 according to the invention can, of course, also be used for other purposes than opening screwed lids 14, such as closing screwed lids 14, and generally loosening or fastening any screwed objects or rotating entire assemblies.
